The game Topalov-Sokolov , Antwerp 1997 went :1 e4 e(2 Nf3 Nc63 Bb5 a64 Ba4 Nf65 O-O Nxe46 d4 b57 Bb3 d58 dxe5 Be69 Nbd2 Nc510 c3 Be711 Bc2 Bg412 Re1 O-O13 Nb3 Re814 Nxc5 Bxc5And Sokolov could eventually equalizeBut , since this game , all games with this line were 1-0 , as one can see inChessBase.com databaseDoes it mean that Open Defence is refuted?I played it recently , and was lucky enough to draw , but never I had the shadowof a winning chanceThen , if it's only to draw , why to choose Open Defence?Other lines , like Berlin Wall , are easier and safer to drawI shall play no more the Open Defence until a BIG improvement
